So I just heard about this convention in DC from April 18-20. It looks like it has an impressive selection of guests including Sean Astin, Jewel Staite, Phil LaMarr, Ernie Hudson and many more. I'm interested in going, and I was wondering if anyone has ever been to this particular con.

I am mostly looking for some firsthand information on the type of crowd that it attracts and whether it would be suitable to take my 8-year old daughter. Any stories would be helpful. Thanks.

Edit: here's the website.
